.IOIIN SIMPSON, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR OF ONE-IIALF TO DIGIITON A. ROBINSON, OFl SAME PLACE,

GRAIN-.SPOU'T'l SPECIFICATION forming part of Letters Patent No. 445,645, dated February 3, 1891. Application filed February 15, 1890- Serial No. 340,655. (No model.)

To all whom it may concern.-

Be it known that I, JOHN SIMPSON, of Min neapolis, in the county of Hennepin and State of Minnesota, have invented'certain Improve- 5 ments in Grain-Spouts, of Which the following is a specification. Y

My invention relates to means for spouting or removing by gravity grain from one receptacle to another, and is particularly adapt o able and useful in elevators for spouting grain from the scale-hopper to the various bins in the elevator; and the invention consists, generally, in two spouts or chutes, pret'- erably made of metal, the upper one piv- 5 otally supported upon the bottom of the scalehopper and adapted to be rotated about said hopper, and the lower one supported upon a suitable frame provided with rollers, so that it may be easily moved about the floor. The

a lower end of the upper spout is adapted t fit into the upper end of the lower spout, which maybe rotated about said upper spout, thereby making a continuous conductor to any part of the floor within acircle described g by the combined lengths of the two spouts. For convenience in weighing grain the upper spout is provided with a counterbalancing-weight to raise the upper from the lower spout, except when the grain is passing through it, all of which is hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a vertical section of a portion of an elevator provided with myimprovements. Fig. 2 is aseotional view on line o: :c of Fig. 1. Fig. 3 is a detail showing the manner ot' connecting' the upper spout to the hopper. Fig. lis a detail l showing manner of constructing the parts of the two spouts where they come together. Fig. 5 is a detail plan view of the counter balancing-weight and ring.

In the drawings, 2 represents a scale-hopper extending from the garner-Hoor 5 to the scale-floor 7 land supported upon suitable weighinglevers 8 and 9, supported by the bolts 10 upon the tloor-timbers 11 and connected with the scales 13. Upon the bottom of the hopper is secured a suitable casting 15, having preferably the upper part 16 constructed flaring to tit onto the bottom of the hopper, and the lower part 17 cylindrical and provided with the annular groove 19. A bar ot iron 18 is preferably provided bent inthe form of a ring, so as to fit into the groove'lf), vand secured in place by means of the bolt 20, one end projecting out far enough to receive the Weight 21. To the bar 18 is securely riv eted the upper spout 23, so that when the band 18 is in place in the groove 19 it supports the spout 23. A lower spout is pro vided, the upper end 26 of which is preferably made Haring or enlarged to receive the end 24 of the spout 23.

Arranged to it in the enlarged end 26 ot' the spout 25 is a seat 27, preferably secured to the inclosing spout, the lower end being contracted so that its diameter is less than the diameter ot' the end 24 of the spout 23, thereby forming a seat for the spout 23 when in use. The spout: 25 is preferably pivotally mounted upon a suitable track or frame 30, supported upon rollers 31, by means of the pivot 32, to facilitate its being moved from one place to another on the floor 33, which is provided with openings 35, leading into the bins 37 forv the reception ot the grain.

On the projecting end of the bar 18 is ad- -justably secured the weight 21, so as to counterbalance the weight of the spout 23, lifting the end 24 from contact with its seat 27 in the spout 25, so thatit normally hangs suspended from the scale-hopper 2, the scales being adjusted to balance the weight of the hopper and the suspended spout.

A slide 39 is arranged inthe casting 15 for opening and closing the outlet from the hopper into the spouts.

In operating the device, the grain being elevated into hopper 2 and weighed by the scales 13, the slide 39 is withdrawn, when the grain rushes into spout 23, its gravity overcoming the weight 21, thereby pressing the end 24 of the spout 23 firmly against the seat 27 in the enlarged end of the spout 25, the other end of the spout 25 being inserted in the opening 35, leading into the bin 37, into which it is desired to conduct the grain. Vhen the grain is all out of the hopper 2, the spout 23 is automatically raised from contact with its seat 27 `by means of the weight21, but not out IOO ot' the spant 25. The spout 23, is adapted to he rotated about the bottom of the hopper 2 upon the bar 18, secured in the annular groove l). The area traversed by the spout 23 when rotated should be free from posts or supporting-timbers 4:1; but outside this circle supporting-timbers may be placed when desired, as the construction and arrangement of the two spouts permit their being used in openings which may be directly behind the posts ll, as shown in Fig. 2. The dotted lines in both Figs. 1 and 2 show different ypositions into which the spouts may be swung. The end 2li of the spout 23 being rotated upon the inner casting in the spout 25, the dust from the grain is prevented from escaping from the spouts into the room, thereby avoiding a common nuisance and great annoyance.

A suitable handle is secured to the spout- 25, to take hold of in moving the spout from place to place.

I claim as my invention- 1. A kgrainconductor comprising, in combination, an upper spout rotatively secured to a suitable support,anindependentlowerspout adapted to receive the loose end of the upper spout in any position in whichit may be and capable of being rotated about said upper spout as a center, and an independent support mounted upon suitable rolls and supporting said lower spout, substantially as described.

2. The combination, with a scale-hopper, of

a counterbalanced rotative spout 23, secured thereto. V

3. The combination, with a scale-hopper for weighing grain, of a grain-conductor comprising two spouts, one secured to and adapted to rotate about said scale-hopper, the other adapted to receive the loose end of said first spout and to be rotated about it, and a counlerbalancing-weight adapted to hold said Iirst groove and provided with Weight 21, and the spout 23, secured to said bar, for the purpose specified.

6. The combination, with the spout 23, of the independent movable spout 2,5, having its upper end enlarged and adapted to receive the spout 23 in any position, the seat 27, secured to the said spout 25, the lower end of said seat being of less diameter than the end of the spout 23, for the purpose specified.

7. The combination, with a scale-hopper, of the casting 15, secured thereto, provided With l the'annular groove 19, bar 18, carrying weight 2l, counterbalanced suspended spout 23, secured to said bar and adapted to rotate in said annular groove, and the spout 25, adapted to receive the loose end of the spout 23, substantially as described, and for the purpose specified.v

8. The combination, with the hopper 2, of the casting 15, having groove19, bar l 8, Weight '21,spouts 23 and 25, and seat 27, substantially as described, and for the purpose specified..

In testimony whereof I have hereunto set my hand this 3d day of February, 1890.
